IC... I tested this with "make show-var 
VARNAME=BUILTIN_X11_VERSION.native", and seeing it return nothing at all 
it confused me. I don't understand the underlying code at all, but by not 
setting it it seems a bit harder to trace errors ("is it undefined by 
mistake, or on purpose?").

"make show-var VARNAME=BUILTIN_X11_VERSION.native" in pkgsrc/x11/xcursor 
(IIRC).

Hm, both these are there:

1)
rfhpc8317% find /usr/openwin/ -name Xrender.h
/usr/openwin/share/include/X11/extensions/Xrender.h

2)
rfhpc8317% grep BuildRenderLibrary /usr/openwin/lib/config/*
/usr/openwin/lib/config/Project.tmpl:#ifndef BuildRenderLibrary
/usr/openwin/lib/config/Project.tmpl:#define BuildRenderLibrary      YES
/usr/openwin/lib/config/Project.tmpl:#if BuildRenderLibrary

Don't hold your breath - seems I ran into some timeout for hacking on 
this, at least for now. ;)
